The spindle 2 is usually struction having a self. lockingfoot and a secured in any desired manner as by means of illustrated inthe accompanying drawings dropping the block therein.

The member 13 is provided with a depending flange 16which, in turn, is formed with opposed slots 17 permittinp,- theintroduction and retention of the flyer wires 15, and serving to lockthe latter in position. To insert a flyer wire into position the blockmay be removed from the spindle or not as desired, the wire beinggrasped between two of the fingers and intro duced under the skirt 16,the thumb being placed on the opposite side of the block after which thearms of the wire are forced towards the thumb and slipped into the slotsor grooves 17. As indicated in my prior applications, above identified,the slots 17 may be provided with wire retaining grooves of any desiredconfiguration. It will thus be seen that the device shown in Fig. 1 maybe readily attached to or removed from a spindle and its associatedbobbin and, in addition, broken fiyer wires may be readily removed andnew ones replaced without disturbing the block or the spindle, and, thatthis repair or new installation may be done on the machine withoutrequiring the removal of the blocks and the separate renewal of thewires. This con struction obviates the necessity of maintaining completeduplicate sets of blocks to permit the removal of the blocks and theirhandling at a point separate from themachine,

for the purpose of refitting with fiver wires. 7

Owing to the relatively short life of the flyer wires, replacements,even under the most favorable circumstances, are required at least onceevery four to six weeks. The delays incident to the stoppage of spinningmachines for the removal of flyer blocks. and replacement with others isan appreciable item in manufacturing costs. With the present novelimprovements, as has been set forth above, it is not necessary to removethe blocks from their spindles as the wires may be in serted or removedby a simple manual operation, without requiring; the use of specialtools or skilled labor. With the fiyer blocks of the present inventionin use any spinning machines operative can readily replace the fiyerwires without waiting; for the services of mechanics usually assigned tothis task. This facility of insertion and removal increases theefiiciency of both the machine and its operative while reducing laborcosts, not only lowering the investment in replacement parts but alsopermitting a lower initial investment in flyer blocks due to theirsimplicity of construction. The flyer block just described is readily fomed by simple machining operations and is susceptible of manufacture onautomatic machines now available.

Referring now to Fig. 2 there is shown a modification of theconstruction shown in Fig. 1. In this construction a central flange 20is provided with an upstanding skirt 21 and with the usual opposed wireengaging slots 22. The member 20 in connection with the skirt 21 forms achannel 23 which is adapted to receive a locking; device such as a screwthreaded nut 24 in threaded engagement with the upper threaded portion25 of the body of the flyer. This construction permits the flyer wire 15to be forced into engagement with the supporting platform 20 and bemaintained thereagainst. The member 24 may be cut away internally asindicated at 26 to prevent cutting of the wires or body of the flyer.

While a lock nut of the screw threaded type has been shown it will ofcourse be appreciated that any suitable locking means may be used, suchas a bayonet joint construction, or other well known locking meansfamiliar to those skilled in the art.

The use of a support with an upstanding slotted flange permits theinsertion of the wire in place and the association of the locking meanstherewith without involving a rotation of the wire itself, which, undercertain circumstances, might be a disadvantage.

The modified construction shown in rig. 3 is similar to that shown inFig. 2 with the exception that the platform support 30 is not providedwith a skirted flange, and the locking; member 31 is provided with adepending portion or skirt 32 and the opposed slots 33. As shown. in thedrawings this locking member is a lock nut having threads 3-1 engagingsimilar threads on the body of the flyer. A bayonet joint or othersuitable looking means may be substituted for the screw thread meanshere shown without departing from the spirit of the invention. Thebayonet joint permits the securing of the tlver wires in place andparticularly where the latter are provided with raised portions or humpsadapted to afford a spring tension against the retaining member. The useof a bayonet joint permits the securing of a locking effect by afractional. turn of the retaining member rather than requiring severalcompleteturns as with a screw threaded assembly.

It will now be appreciated that there has been provided a plurality offly-er block constructions in which demo-untable fiyer wires are adaptedto be positioned and which are particularly suited for use with spindletips of uniform diameter.

In accordance with the provisions of the patent statutes 1 havedescribed the principles of operation of my invention, together with thedevice which I now consider to represent a preferred. embodimentthereof; but I desire to have it understood that the devices shown areonly illustrative of the basic concept of the present invention. andthat the said invention may be carried out by other means.
